Endoscopic Ultrasonographic Study of the Azygos Vein Before and After Endoscopic Obliteration of Esophagogastric Varices by Injection Sclerotherapy

Abstract

Using EUS and Doppler EUS, hemodynamic studies of the azygos vein blood flow can be performed, allowing the monitoring of the effects of EIS and variceal obliteration on the superior portosystemic collateral circulation. The clinical significance of the observed changes in azygos blood flow that occur with variceal obliteration should be investigated in further studies and correlated with short-term and long-term outcome.
